BEx1 valve box
Powered by FESTO and Exepd
The 3 in 1 solution provides plant and machine manufacturers for the first time a decentralized and compact solution with Profinet or Modbus TCP/IP to control pneumatic actuators for hazardous area Zone 1/21
High flow rate in a small space - State-of-the-art bus technology - Unique: The structural design
Tested system solution from
Innovative and compact Ex
IO modules with bus connection
Operationally proven Ex i valve terminal
Certified system installation in Ex e field housing
Applications
- Paint shops
- Pharmaceutical plants
- Chemical plants
- Tank farm
- Bulk materials handling systems
- Mixing / grinding plants
- Industrial heating / cooling systems
- Sewage treatment plants and much more
Integration
- The Ethernet connection (Profinet or Modbus TCP/IP)
is executed in increased safety Ex e.
- Ex media converters or fieldbus couplers in the safe area are not required and the full Ethernet performance can be used.
- No IO modules required on the PLC
- The BEx1 module does not have to be parameterized or configured and behaves transparently in the control I/O.
Installation scheme
Customer benefits
Compact - Simple - Fast
- Central Ethernet connection, central compressed air connection
- The compact housing enables optimal decentralized installation in the system and guarantees short distances to the sensors and the pneumatic actuators.
- No compressed air tubing inside the housing.
- Cost savings and less installation effort
The ATEX certified system in the field housing is designed for installation in Zone 1/21
The BEx1 IO valve box combines bus nodes, isolating switching amplifiers, intrinsically safe IO channels and the pneumatic valve terminal.
Functions
- 8 outputs to 8 valves 3/2 way pre-wired
- 16 Namur inputs for position feedback
- 8 DO(AIO)*
*Individually adjustable as DO, AI, AO or Switching Mode
